Hi welcome to just answers , my name is***** leak of antifreeze will cause the reserved bottle to go low and boiled over, if you see antifreeze in the floor near the pass/ side then there most be a leak, possibly a hose or heater core or the engine head . First thing you need to do is a cooling pressure test with a pressure pump this is a tool that puts pressure on the radiator and engine if there is a leak it will show right away, door have a coolante pressure tester?

no I dont . what should I do after that. it fluded the ground at once at idle . The radiator was dry and it immediatley ran hot but the reserve tank was still full .

ok some times when there is vapor lock on the radiator cause by a leak anywhere in the cooling system the vapor pressure on the radiator will prevent fluid from the reserved to fill up the radiator

You need to have a cooling system pressure test done at any repair shop as soon as possible because this can cause engine failure do to overheating.
